Abstract

Temperate grasslands act as carbon sinks and thereby play an important role in the global carbon cycle. Carbon stabilization by water-stable soil aggregates (conglomerates of soil particles that maintain their form when subjected to water disturbance) is a proposed mechanism for long-term carbon storage. Soil disturbances and the cultivation of grasslands have been shown to change the abundance and stability of soil aggregates. This study investigates whether the restoration of formerly cultivated fields back to grasslands influences the soil’s ability to store carbon. Specifically, we examine the impact of prolonged management of restored grasslands on carbon content in soil aggregates.

The role of soil aggregates in sequestering carbon in restored temperate grasslands
